“…While the potential energy surfaces used in this work have already been presented in other publications - [30] for 240 Pu and [47] for 236 U -we recall them for the sake of completeness. Figure 1 thus shows the total potential energy V (q) entering the collective Schrödinger equation of Eq.…”

“…It describes superasymmetric fission strongly related to cluster radioactivity and the saddle point in the superasymmetric valley reaches more than 30 MeV. It is noted that the overall topography of the 2D PES is similar to that calculated with the Skyrme SkM* functional [55]. (Color online) Contour plots for the sections of the 3D PES of 236 U.…”

We have calculated the three-dimensional potential energy surface (PES) for the fission of compound nucleus 236 U using the covariant density functional theory with constraints on the axial quadrupole and octupole deformations (β2, β3) as well as the nucleon number in the neck qN . By considering the additonal degree of freedom qN , coexistence of the elongated and compact fission modes is predicted for 0.9 β3 1.3. Remarkably, the PES becomes very shallow across a large range of quadrupole and octupole deformations for small qN , and consequently, the scission line in (β2, β3) plane will extend to a shallow band, which leads to a fluctuation for the estimated total kinetic energies by several to ten MeV and for the fragment masses by several to about ten nucleons.
